The aerobic filter material disclosed by the invention is prepared by mixing and sintering three main materials, namely clay, zeolite and calcium carbonate; the preparation process comprises the following steps: firstly, uniformly mixing the clay, the zeolite and the calcium carbonate according to a weight ratio of 1: 2: 2 to prepare a mixture; putting the mixture into a closed furnace, and carrying out sintering treatment to convert the mixture into an assembly; then, the assembly body is subjected to laser drilling machining; then carrying out fragment granulation, so that the particle size is uniform and the viscosity is not influenced; then, an assembly obtained after fragmentation and granulation is covered with rice in a certain proportion, ant nest-shaped small holes are formed, and the adsorption, filtration, degradation and catalyst effects are enhanced; and finally, adding a proper amount of surfactant and catalyst to realize catalytic oxidation removal and recovery of pollutants in the filter mater
